I'm trying to run BFD for OSPF between 6500E running version 12.2.33 SXH and Nexus 5596UP running Version 6.02. The Nexus 5596 has L3 cards and the correct licence.
Here are the config
6500:
_________
!
interface GigabitEthernet7/17
ip address 30.30.30.1 255.255.255.0
no ip redirects
ip ospf network point-to-point
ip ospf bfd
end
!
router ospf 300
log-adjacency-changes
passive-interface default
no passive-interface GigabitEthernet7/17
network 30.30.30.0 0.0.0.1 area 0
network 100.100.100.0 0.0.0.255 area 0
bfd all-interfaces
Nexus 5596:
_________
feature bfd
!
interface Ethernet1/17
no switchport
speed 1000
no ip redirects
ip address 30.30.30.2/24
ip ospf network point-to-point
ip router ospf 300 area 0.0.0.0
ip ospf bfd
!
router ospf 300
bfd
!
Now, BFD neighbor is not even showing on the 6500
N5596# sh bfd nei
OurAddr NeighAddr LD/RD RH/RS Holdown(mu
lt) State Int Vrf
30.30.30.2 30.30.30.1 1090519042/0 Down N/A(3)
Down Eth1/17 default
C6500#sh bfd nei
OurAddr NeighAddr LD/RD RH/RS Holddown(mult) State Int
Cat6500#
What did I miss?
Thanks for your help

Hi,
When I've used BFD on the Catalyst 6500 with both 12.2SXI and 15.1SY you also need to configure bfd interval milliseconds min_rx milliseconds multiplier interval-multiplier under the interface.
See How to Configure Bidirectional Forwarding Detection for detailed configuration steps.

Is the OSPF peering up and working?
If yes, 12.2.33 SXH is pretty old and I am thinking even though it takes the commands it may not support BFD.

Thanks for your reply. That was the first thing I checked. Cisco feature Navigator confirmed it's supported.
